我正在尝试从右到左制作import UIKit
class ViewController: UIViewController {
@IBOutlet weak var lblGetMsg: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
@IBAction func btnGetMsg(sender: AnyObject) {
let url = NSURL(string: "http://ip.jsontest.com")
let task = NSURLSession.sharedSession().dataTaskWithURL(url!) {(data, response, error) in
print(NSString(data: data!, encoding: NSUTF8StringEncoding))
self.lblGetMsg.text=(String(data: data!, encoding: NSUTF8StringEncoding))
}
task.resume()
}
}
幻灯片。
我已经关注this tutorial，发现从左到右滑动的DrawerLayout非常令人满意。
当我将DrawerLayout的{{1}}更改为gravity时，它会从右向左滑动，但是，汉堡按钮不再正常工作，它会显示{{1}当我试图触摸它时。
这是修改后的切换功能
android.support.design.widget.NavigationView那么..如何让汉堡按钮再次工作？
更新
这是主要布局的XML文件
right这是我的主要课程
No drawer view found with gravity LEFT2016年2月2日更新
尝试将抽屉视图更改为// Initializing Drawer Layout and ActionBarToggle
drawerLayout = (DrawerLayout) findViewById(R.id.drawer);
ActionBarDrawerToggle actionBarDrawerToggle = new ActionBarDrawerToggle(this,drawerLayout,toolbar,R.string.openDrawer, R.string.closeDrawer){
@Override
public void onDrawerClosed(View drawerView) {
// Code here will be triggered once the drawer closes as we dont want anything to happen so we leave this blank
super.onDrawerClosed(drawerView);
}
@Override
public void onDrawerOpened(View drawerView) {
// Code here will be triggered once the drawer open as we dont want anything to happen so we leave this blank
super.onDrawerOpened(drawerView);
}
//Added the lines below, tried solutions online but fail..
@Override
public boolean onOptionsItemSelected(MenuItem item) {
if (item != null && item.getItemId() == android.R.id.home) {
if (drawerLayout.isDrawerOpen(Gravity.RIGHT)) {
drawerLayout.closeDrawer(Gravity.RIGHT);
} else {
drawerLayout.openDrawer(Gravity.RIGHT);
}
}
return false;
}
};
..但这是一个坏主意，因为没有任何变化。试着将<?xml version="1.0" encoding="utf-8"?>

，更糟糕的是因为没有滑动菜单..
尝试改变RIGHT
NavigationView将LinearLayout更改为onOptionsItemSelected，“NOPE”，代码说明了......
答案 0 :(得分：1)
在导航视图中尝试此操作
机器人：layout_gravity =＆＃34;端＆＃34;取代android：layout_gravity =＆＃34; right＆＃34;
<android.support.design.widget.NavigationView
android:id="@+id/navigation_view"
android:layout_height="match_parent"
android:layout_width="wrap_content"
android:layout_gravity="end"
app:headerLayout="@layout/header"
app:menu="@menu/drawer"
/>
//在java活动文件中添加这些行，它将起作用
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
if (mDrawer.isDrawerOpen(Gravity.RIGHT)) {
mDrawer.closeDrawer(Gravity.RIGHT);
} else {
mDrawer.openDrawer(Gravity.RIGHT);
}
return true;
case R.id.action_settings:
return true;
}
final update:
我更改了示例项目中的一些行（MainActivity.java），现在它正在运行，使用此代码。
别忘了写android：layout_gravity =＆＃34; end＆＃34;代替android：layout_gravity =＆＃34; start＆＃34;在你的xml文件中。

答案 1 :(得分：0)
对于仍然存在此问题的任何人： 您应该在NavigationView中设置以下行：
android:layout_gravity="start"
，这在您的Java中：
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this,drawerLayout,toolbar,R.string.navigation_drawer_open,R.string.navigation_drawer_close){
@Override
public boolean onOptionsItemSelected(MenuItem item) {
if(item != null && item.getItemId() == android.R.id.home){
if (drawerLayout.isDrawerOpen((Gravity.END))) {
drawerLayout.closeDrawer(Gravity.END);
} else {
drawerLayout.openDrawer(Gravity.END);
}
}
return false;
}
};
对我有用。
